Now a user-interaction designer in California, Leftwich relays this information on these drawings:
"The M-Aura bitmap was created in 1987 on my 128k Macintosh, using MacPaint. It was mostly done by hand, but I generated the source of the wave image at the bottom using some early match application. But I remember that every pixel and line was cleaned up by hand, as there were a lot of irregular jaggies, etc...
I created it for the October 1987 cover of M-Aura, the monthly newsletter of North Texas Mensa (Dallas, where I was living at the time). I'd gone to the School Of Design at the Kansas City Art Institute, where Los Angeles graphic designer April Greiman was one of the alumni. I was inspired in part by her digital piece, which had been printed in the industrial design magazine, I.D."
